Measuring pipettes including integral or encapsulated filters, as well as methods and apparatuses for forming the same, are provided. A filter material (e.g., a discrete element in solid form) or a filter material precursor (e.g., a foamable thermoplastic composition and a blowing agent) to be introduced into a hollow interior of a softened thermoplastic material present within a mold during pipette fabrication. A pipette includes a filter element comprising foamed polymeric material within a mouthpiece region, wherein an outer portion of the filter element is bound to or encapsulated in an inner wall of the mouthpiece region. A filter material precursor may be supplied coaxially with a tubular flow of thermoplastic material into the mold, may be supplied laterally through a mold wall, or may be injected into a molten thermoplastic pipette forming material upstream of an extruder outlet.

The invention relates to a holding apparatus for holding a pipetting container, in particular a serological pipette, at a pipetting apparatus, comprising a tubular connecting section that is configured to hold a tube-shaped end of a pipetting container in a pipetting position by means of a clamping connection, a clamping connection device that is arranged at the connecting section and that comprises a spring device for the establishment of the clamping connection and an air chamber device for releasing the clamping connection by means of a vacuum. Furthermore, the invention relates to a pipetting apparatus with that holding apparatus.

The present technology is directed to extraction devices, systems, and methods for controllably withdrawing and transferring fluid samples, such as blood, from a sample collection container to a testing device. For example, some embodiments of the present technology provide fluid extraction devices that include a fluid control module, a housing containing a receiving element and a suction element, and an actuator. To transfer blood from a sample collection container to a testing device, a user places the sample collection container over the receiving element and inserts the testing device into an outlet of the fluid control module. The user then pushes a lever or otherwise actuates the actuator, which automatically withdraws a predetermined volume of blood from the sample collection container and transfers it to the testing device positioned at the outlet of the fluid control module.

According to an example aspect of the present invention, there is provided a method, comprising: providing a wearable electronic device that is configured to be worn by a user of a laboratory device; by means of the wearable device, retrieving user data that is specific to said user; and on the basis of the retrieved user data, providing a functionality for control of the laboratory device.

The present invention relates to a pipette dispensing block with an improved design for the piston chambers. In a multichannel pipetting block with a grid or array of pipetting piston of any order, the individual piston chambers are individually manufactured using the injection molding process. The individual piston chambers are assembled into a grid or single line array and held together by upper and lower plates in combination with either stabilizing posts or walls. The piston chambers are designed and assembled with a dual o-ring design at the tip and a tip sealing gasket at the bottom to provide the air-tight seal that is required for optimum pipetting performance. When combined with pistons and a motor-driven lifting plate for the pistons, the entire assembly forms a forms a multichannel pipetting block

A sliding seal [4] is operated within a bore [1] by means of magnetic attraction to an externally positioned and operated ring magnet [10] thus enabling a burette to be filled through the jet [3] like a syringe and remove the need for a control tap.

A gripper having a mechanical coupling that can be connected to a pipetting tube, at least one fluid channel extends from the coupling and a negative pressure can be transmitted, the gripper having at least one suction cup that is connected to the coupling through the at least one fluid channel as a result of which the negative pressure can be transmitted from the coupling to the at least one suction cup, and the at least one suction cup in the intended use position of the gripper is aligned such that a rim of a suction cup of the at least one suction cup is aligned in a substantially vertical plane.

A telescoping electric pipette controller has a handle, a head end portion, an outer shell and a manual retainer. One end of the head end portion is arranged in an end portion of the handle in a penetrating manner, the outer shell is sheathed over an outer surface of the end portion of the handle, and one end portion of the manual retainer is rotatably connected to the outer shell. By means of opening or fastening the manual retainer, one end portion of the manual retainer is released outwards or pressed inwards against the head end portion, allowing extension and retraction of the head end portion relative to the handle. The extension and retraction, as well as the locking of part of a grip structure, are controlled by means of a switch, allowing the grip to change the length within a specific range.

A disposable test cartridge and method for a point-of-care analyzer includes a cartridge body having a plurality of chambers where each of the plurality of chambers has an opening at a top of the cartridge body, a cartridge cover connected to the cartridge body where the cartridge cover has a capillary-receiving aperture, a capillary wiper disposed within the capillary-receiving aperture where the capillary-receiving aperture is aligned with one of the plurality of chambers of the cartridge body, and a capillary element removably insertable into the cartridge cover where the capillary element has a capillary tube that extends into the capillary-receiving aperture and through the capillary wiper where a tip portion of the capillary tube extends into the cartridge body.

A protector assembly for handling, storing and transporting donor tissue in a transfer pipette includes a distal cap and a proximal plug that are respectively engageable with opposite ends of the pipette. Structurally, the pipette includes a distally tapered fluid chamber which is in fluid communication with an extension tube. The distal cap is dimensioned for friction engagement with the fluid chamber of the pipette and it is formed with a plurality of vents to establish fluid communication through the vents with the fluid chamber. On the other hand, the proximal plug is dimensioned for a friction engagement with the extension tube to prevent leakage of solution from the fluid chamber of the pipette when the proximal plug is engaged with the pipette. In combination, an engagement of the protector assembly with a pipette holding a donor tissue will protect and preserve the donor tissue during handling and transport.
